Replacing older alum. patio door sliders. One roller is broken as can be seen in side view

A home owner from San Jose, CA says:

The alum housing for the roller is 2" in length (see pic 2). It looks like it may be "Barton Kramer" but I could not find an exact match on their website. I need one roller for sure but preferably two. Or any replacements that would fit in the pictured door frame. The adjustment hole is 3/4" from bottom of frame (see pic 3). The hole for the door frame screw is 1 3/16" from bottom of frame. The roller frame is 3/4" wide (see pic 1). Pic 4 is a bottom look of where the roller slides into place. Is this enough to determine what might work? I am John I would appreciate any guidance you can provide. Thank you.

Hello, thanks for writing in. Before I make a recommendation, could you please tell me the width and height of the outer housing? I'd also like to know the diameter of the wheel. Thanks!

I hope you can read the measurements. Please let me know if you need more details or clarification. Thank you. John

Thanks for getting back to me with those measurements. I believe the 81-071 is the closest match that we have, although I unfortunately can not guarantee that it will work as a substitute for your roller. I'm sorry I wasn't able to find a more exact replacement.

Thank you for trying. I think the track is in very bad shape anyway so I will have to reach out to a pro.
